CYSTOSCOPE.

T0 all whom it may concern Be it known that I, iJULIUS LONDON, residing at New York, in the county of Bronx and State of New York, have invented certain new and useful Improvements in Cystescopes, of which the following is a specification.

This invention relatesto a device intended to be used for the examination of parts of the body by physicians and surgeons, particularlyv for the treatment of diseases .of various'kinds on parts of the body not easily accessible for examination and treatment.

The device comprises an elongated tubular sheath adapted to be thrust into the Opening, cyst, or other cavity of the body. The inner or distal end is open and provided with suitable illuminating means, such as an electric lamp or the like, and appropriate accessory instruments may be introduced through the Atube or sheath for eifecting various operations. A telescope extends through the sheath into position for close inspection of the parts being operated upon.

A particular object of the present invention is to provide an opening straight through the sheath for conveniently recelving the various accessory implements, and at the same time so shape the telescope that a vision may be obtained of the parts being operated upon by the accessories throughout the period of the operation, if desired.

Other objects and aims ofthe invention,

more or less specific than those referred to above, will be in part obvious and in pointed out in the course of the following description of the elements, combinations, arrangements of parts and applications of principles, constituting the invention; and the scope of protection contemplated will be indicated in the appended claims.

In the accompanying drawings which are to be taken as a part of this specification, and in which I have shown a merely preferred form of embodiment of the invention, Figure 1 is a side, elevational view through the sheath portion of the instrument, portions being illustrated in section for'disclosing the presence of an obturator; Fig. 2 is a longitudinal, sectional view of the sheath with the obturator withdrawn and illustrating the telescope and an accessory implement in operating position therein; Fig. 3 is an enlarged, detail, sectional view of the outer end portion of the sheath and telespeeication of Letters raient.-

scope; Fig. 4 is an end view of the part shown in Fig. 3; Fig. 5 is an enlarged, detail, sectional view onr the plane of line V-V of Fig. 4; Fig.6 is a transverse, sectional view illustrating a modification, the section being taken on theplane of line VI-VI of Fig. 7 and Fig. 7 is a top plan view, partly in section of the structure illustrated in Fig. 6; and Fig. 8 is a detail, sectional view illustrating a modification. Referring to. the drawings for a detailed description of the structure illustrated, the reference character L indicates the sheath. This is of any appropriate cross-sectional contour, and at its inner end is provided with the usual beak 1, terminating in a rounded surface 2. A fenestral opening 3 is providedvon the convex side of the beak, and an electric lamp 4 is provided within said fenestral opening, preferably projecting toward the heel of the beak so as to project its direct rays into closer proximity with the inner end of the telescope, as will be presently referred to. The lamp 4 preferably projects somewhat without the fenestral opening, so that the rays may emanate in various directions, though obviously this detail maybe varied according to requirements.

The current carrying circuit for the lamp 4 may be arranged in any suitable manner.

as is. well known in this art, and need not be specifically described in connection with the present invention.

The opening through the sheath is substantially straight and uninterrupted throughout its length, except at' the outer end where an enlarged pocket 5V is formed forreceiving a closure portion 6 of the obturator or of the telescope, or of accessory implements which may be extended through the sheath.

Ihe obturator illustrated in Fig. 1 comprlses a straight bar 7 having a handle portion 8 formed as an extension of the closure part 6. The inner or distal end is provided with a head shaped substantially to fill the distal end of the sheath, and its outer surface is rounded and projects slightly beyond the end of the tubular portion of the sheath so as to complete a rounded surface for said end to facilitate insertion of the device. After the device is inserted, the obturator is withdrawn and the telescope and accessory implements may then be nserted in its stead for perfecting an operation.

The telescope is illustrated at G and comprises a straight tubular portion of a length so that its inner end projects slightly beyond the inner end of the sheath. The outer end is provided with la closure portion 10 for fitting closely within the pocket 5 of the sheath. The tubular portion is somewhat smaller in diameter than the inner diameter of the sheath, and is arranged so as to lie close to one wall of the sheath and leave ample free space within the sheath between itself and the opposite wall of the sheath for the insertion of accessory implements, as clearly indicated in Fig. 2. A suitable opening 11 is provided through the closure portion 10 for receiving the accessory implements. A

At the outer end of the telescope, beyond the closure portion 10, alateral extension 12 is provided, and an eye-piece 12L is provided at the end of the-extension, preferably arranged laterally to said extension or with its axis parallel to the axis of the tubular main portion of the telescope. A suitable prism 13 is arranged within the extension 12,

aving surfaces 14 and 15 for enabling vision through lens 16 of the eye-piece, through the extension 12, and through the lenses 17 in the main or tubular portion of the telescope. The extension 12 may be ofany l. desired length so as to enable convenient use thereof without interference with the operation of the accessory implements. 'Y

The accessory implements, as H, referred to may be of a wide range of types, and, since the opening through which they are inserted is straight and uninterrupted, they may be of substantially straight and rigid construction, the advantages of which will be readily understood by those skilled in this art. Scissors, dilators, snares or forceps with differently shaped tips, hooks, etc.,

`may be readily manipulated by means of the operating handle .or the like appropriate,

structure 18 illustrated in Fig. 2. These implements may be positively and easily operated through the straight opening through .the sheath, and their movements closely 1nspected, throughout the operation, through the telescope, the operation being lighted the while by the lamp 4.

In lieu of the single prism 13 above described, it is apparent that a pair of mirrors 19 and 20 may be arranged within the extension 12 to the same end, and likewise one or more lenses 21 may be arranged in the extension between the mirrors, if desired. It will be understood that for the mirrors 19 and 20 separate prisms may be employed, if preferred. The extension may be of any construction, but is preferably formed by two channel-shaped members having their flanges overlapping and screwed together, as illustrated in Fig. 5.

Suitable valve controlled openings 22 and 23, as in Figs. 6 and 7, may be provided at the outer end of the sheath as is common in connection with these devices for irrigating, and like purposes. v

In order to obtain a more perfect inspection of the parts being operated upon, it is contemplated by this invention that the telescope G may be constructed as a stereoscope, and to this end it may comprise a pair of tubes 24, as best seen in Figs. 6 and 7, each tube being provided with lenses and with an extension 25 at its. outer end, similar to the extension 12 above described, and each extension having an eye-piece 26. rlhe eyepieces are spaced apart so as to accommodate themselves to the two eyes of the operator.

The details of construction and the relative arrangements of parts at the distal end portion of the device may be varied at will to meet different requirements without affecting practicability or efficiency of the olfset eye-piece of the telescope. It is apparent also that though the lenses 17 are shown and described to be carried in a tube formed separately from the sheath so as to be removable therefrom, they may be carried within the sheath without the use of the separately formed -tube if desired, the extension 12, in such instance being carried by the sheath either detachably or not, as may be required.

The opening 11 of closure 10 may be made to form a tight joint with the accessory implements,l if desired, so that a distending fluid may be employed during the use of the implement, or for other purposes, as may be re uired.

s many changes could be made in this construction without departing from the scope of the following claim. It is intended that all matter contained in the above descriptionI or shown /in the accompanying drawing shall be interpreted as illustrative only and not in a limiting sense.
